The above and other objects, features, and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, which are not intended to limit the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

The quality of signals transmitted and received between the mobile telephone terminal and the mobile telephone system can be measured by a quality measurement module. Information on the quality of each signal measured by the quality measurement module can be recorded in a call log file for each call. The bad call event defined here refers to a call that has a problem in a call attempt, for example, a call failure, a call drop, or the like.

FIG. 1A is a configuration diagram of a communication fault analysis apparatus according to an embodiment of the present invention. 1A, an apparatus for analyzing call failure according to the present invention includes an event extraction unit 102, a user information input unit 104, a parameter extraction unit 106, an analysis information generation unit 108, and an analysis information output unit 110 ). The analysis information output unit 110 may further include an analysis information searching unit 112.

The event extracting unit 102 extracts the call failure event information from the call log file. As described above, information on the quality of each signal transmitted and received between the mobile telephone terminal and the mobile telephone system is recorded in the call log file. That is, the call history file may record call history between all terminals and the mobile phone system. In addition, during a call attempt, a call failure or a break in the call may occur. In this case, a call having a problem during a call is defined as a bad call event. The event extracting unit 102 extracts information on a call failure event from the call log file. The bad call event information may include at least one of call start time information, call end time information, and call result information of a bad call event. That is, the event extracting unit 102 can extract the call failure event and the information about the fault from the call log file.

 The user information input unit 104 performs a function of receiving user information on a call failure event. The user information means information on a communication environment for a bad connection event and information related to a bad connection event. Preferably, the user information may include registrant information, occupancy information, business entity information, terminal information, system information, service information, and currency type information. More specifically, the registrant information is the name of the registrant who entered the user information, and the number information may be the registrant's number. The provider information may be the name of the service provider providing the communication service, the terminal information may be the name of the terminal where the faulty event occurred, and the system information may be the name of a communication service such as LTE or WCDMA. The service information may be a service type such as voice or data. The call type information means protocol information used to transmit a signal.

The parameter extracting unit 106 performs a function of extracting a communication quality measurement parameter of a communication fault event. The communication quality measurement parameter means a parameter to be measured for use in designing, configuring, operating, and maintenance of a communication system. The communication quality measurement parameter may preferably include at least one of a signal strength parameter, a downlink parameter, an uplink parameter, an MOS parameter, and a throughput parameter.

For example, the signal strength parameter may include an RSRP parameter, an RSRQ parameter, and a SINR parameter as parameters relating to signal strength between the terminal and the base station. It may also include uplink and downlink parameters related to uplink and downlink MCS information. MOS parameter means a parameter used as a reference for voice quality in VoIP service. The throughput parameter means a parameter related to the data transmission throughput.

The communication quality measurement parameter for the bad call event can be measured by the quality measurement module and can be included in the call log file. The parameter extracting unit 106 can extract the communication quality measurement parameter from the call log file.

The analysis information generation unit 108 performs a function of generating event analysis information using the communication quality measurement parameter. The event analysis information refers to information related to the analysis result of the bad event. The event analysis information may include information on cause of occurrence of a bad call event and a recommendation for action.

The information on the cause of the occurrence of the bad call event may be determined according to the communication quality measurement parameter. For example, when the value of a parameter such as the RSRP parameter, the RSRP parameter, or the SINR parameter is equal to or less than a predetermined reference value, information on the cause of a bad call event can be automatically generated as a result of the parameter.

The Recommendation Recommendation refers to the action to resolve the bad call event received from the measurer by providing the cause of the bad event.

That is, the analysis information generation unit 108 may generate event analysis information using the communication quality measurement parameter or receive event analysis information generated by another module. Accordingly, the event analysis information may include information on the cause of the occurrence of the bad call event and a recommendation for the action.

For example, it is possible to input a recommendation to adjust the Naver confirmation and the corresponding coverage overlap for information on the cause of the call failure event of the call failure due to the instantaneous incoming PCI in the call duration.

The analysis information output unit 110 outputs event analysis information corresponding to a bad call event among the generated event analysis information using user information and communication quality measurement parameters. According to an aspect of the present invention, event analysis information may be generated for each faulty event. When a new call failure event is input, the analysis information output unit 110 may output event analysis information corresponding to the previously-input call failure event among the previously generated event analysis information.

The analysis information output unit 110 may further include an analysis information searching unit 112. The analysis information searching unit 112 classifies the event analysis information having user information matching the bad call event among the generated event analysis information. Then, event analysis information having the same communication quality measurement parameter as the newly input call poor event among the classified event analysis information can be retrieved. In addition, the retrieved event analysis information can be output.

For example, the analysis information searching unit 112 may classify event analysis information having the same system information and currency type information among the event analysis information. The event analysis information can be retrieved by referring to the signal strength parameter, the downlink parameter, the uplink parameter, the MOS parameter, and the throughput parameter among the classified event analysis information. If the above classification and search result can provide the previous event analysis information, the information on the cause of the bad event and the recommendation for the countermeasure can be output. If the previous event analysis information can not be output, the information on the cause of the bad event of the call generated by the analysis information generation unit 108 and the recommendation for action are output.

The event analysis information is typed according to the user information and the communication quality measurement parameter and the event analysis information according to the type is outputted so that the event analysis information is quickly provided to the call poor event similar to the previous bad call event .
